BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to watch cases, in particular to a wristmounted watch with a watch case having separable components of a mainbody and a surrounding protective frame.

2. Background Information

Horology is the science of time, timekeepers such as clocks and watchesand of timekeeping. The present development is directed the sub-set ofhorology directed at watches. Fine watch making is a science and an art.Watches, as opposed to clocks, have been said to have originated inWestern Europe around the end of the fifteenth century with thedevelopment of pocket watches. What made pocket watches different fromclocks was the mechanism used to drive the watch, collectively referredto as the watch mechanism or more commonly the watch movement. The watchmovement of the pocket watch used a balance wheel, hairspring and amainspring. The clocks of the time relied on a combination of counterweights and a swinging pendulum. From the pocket watch, the wrist watchwas developed.

Both pocket watches and wrist watches have a watch case that houses thewatch movement, the stem or crown, the watch face or dial, the hands,and the watch mounting structure. The watch case also supports thecrystal and the bezel, but these components may better be classified aspart of the watch case itself. It has been suggested that if one were tocompare the watch to the human body, the movement would be the brain,the dial would be the face, and the watch case would be the body.

A watch case is the immediate expression of the movement it contains andprotects. It has been noted that the watch case is the part of the watchthat the user touches, the part the user feels against his skin.Therefore, it is proposed that the watch case must have a harmoniousshape, even that the watch case suggest a certain sensuality, and thatthe watch case convey its presence and mirror the curves of its wearer'swrist.

The mounting structure of a watch case generally differs depending uponwhether a pocket watch or wrist watch is intended. For a pocket watchthe mounting structure is generally an eyelet or ring of some type forreceipt of a watch chain. For a wristwatch configuration the mountingstructure is typically formed by a pair of lugs on each end to which abar (also referred to as a pintle) is attached. The bar may be pressfit, screwed in, a spring biased structure, or any attachment mechanismand it is adapted to receive straps that extend around the user's wrist.It is possible that the bar may be integral with the lugs which canchange the structure of the associated straps.

The bezel is generally defined as the ring that surrounds the watch faceor dial. The bezel generally protects the crystal, and in some cases mayhold it in place. The bezel is often rotating relative to the watch faceto provide other functionality such as for easy time measurementfunctions. The bezel can also be considered as part of the watch case asit has a protecting function associated with the watch case.

The crystal of a watch is the transparent cover used to protect thewatch face and hands. The crystal can be made of a number of transparentmaterials including plastic, glass, crystallized aluminum oxide, etc.Scratch resistant coatings and mar resistant coatings may also be used.As with the bezel, the crystal can be broadly categorized as a part ofthe watch case due to the protective functionality.

The dial, or face, of the watch is the background against which thehands of the watch move. The hands of the watch are coupled to and movedby the movement mechanism. Dial and hand making is an art and a craft inits own right that demands considerable expertise. Visually, the dialmust satisfy a dual requirement: it must be pleasing to the eye andlegible at a glance. A host of information must be harmoniously conveyedvia the relative position of the hands on a dial surface. This on asurface that often barely exceeds a few square centimeters. Often a dialis separated into several sections and, beyond its refinement and beautythe dial must highlight and distinguish these different zones. Thus finewatch dial-maker must master these artisanal techniques.

The stem or crown is the manually actuated mechanism for adjusting thehands of the watch and can be used for winding a movement. The crowntypically extends through the watch case so as to be accessible by theuser.

Innovation in the watch making art related to the watch case is evidentin the U.S. Patent and Trademark Office records. For example there areabout three hundred (300) distinct U.S. Patents directed specificallytowards the “subject matter relating to timepieces . . . wherein thetimepiece incorporates a special enclosure or upholding means for thetimepiece contents within the enclosure.” {Class 368 subclass 88 of theUnited States classification system which is noted as 368/88.}Similarly, there have been about ninety (90) patents wherein the subjectmatter includes specific means for inclosing or containing the works ofa timepiece and further including means to increase the modes of utilityof a timepiece (368/277). Separately, there have been well over threehundred (331 at the time of filing the parent provisional application)patents to date wherein the subject matter includes specific means forenclosing or containing the works of a timepiece and further includingmeans for carrying the case on the wrist of the user (368/281). Theseclassifications are certainly not exhaustive of the innovations in thisarea, but this is representative of the number of innovations over theyears relating to certain aspects of watch case construction.

DESCRIPTION OF THE PREFFERED EMBODIMENTS

FIG. 1 is perspective views of a watch 10 according to one embodiment ofthe present invention with part of the watch case removed for clarity ofselected elements. FIG. 9 is an exploded view of the watch 10. The watch10 includes a watch movement 12. The movement 12 is preferably a highgrade mechanical movement and is of known construction. The movement 12references the completed, finished individual mechanism which isresponsible for keeping time.

An “ebauche” is often understood to mean a “raw” or unassembled,unfinished movement, including the major structural components (plates,bridges) and sometimes parts of the wheel train and other moving parts.A caliper is the collective name given to a series of movements of thesame design. Many watch companies will purchase complete movements froma major supplier, while some watch companies will purchase an ebauchefrom a major supplier, polish and decorate the parts (i.e. finish theparts), and assemble it with standard parts to create a higherquality-controlled movement than the stock ready-made movement. Furthercompanies purchase ebauches, finish them to a high standard, modifyparts of the movement, and add custom components like an upgradedescapement assembly to create what can be called a custom version ofthat movement.

The present invention is not restrictive of any of these manufacturingtechniques. The movement 12 can be of any conventional design whetherformed completely in-house, modified from a “stock movement” or acompleted third party movement, such as from ETA SA Manufacture HorogereSuisse, known as ETA (see www.eta.ch) or Lemania. The details of themovement 12, in general, are not part of the present invention and areknown to those of ordinary skill in the art.

The watch 10 includes a dial 14 supported on the watch movement 12 andhands 16 moveable by the watch movement 12. The dial 14, or face, of thewatch is the background against which the hands 16 of the watch 10 move.The hands 16 of the watch 10 are coupled to and moved by the movementmechanism 12 as known in the art. The illustrated hands 16 and dial 14are not intended to be restrictive of the possible dials and hands thatcan be utilized with the present invention.

The watch 10 includes a watch case receiving the watch movement 12. Thewatch case includes a cylindrical main body 20 configured to receive thewatch movement 12 therein, a bezel 24 supported on the main body 20, acrystal 26 supported by the main body 20 and protected by the bezel 24,and a frame 30 receiving the main body 20.

The main body 20 includes generally machined annular cylindrical portionand an attached bottom plate 22 secured thereto in a conventionalmanner. The attachment of the bottom plate 22 to the body 20 and thewatch movement within the annular cylindrical portion of the body 20 isconventional. The main body can be formed out of a number of materials;however metals such as stainless steel provide the durability andaesthetic finish necessary. The present invention allows the main body20 and the associated watch movement to be formed of material that bestsupports the movement. For example 316 steel materials, or material thatis anti-magnetic to protect the movement 12 timing.

The bezel 24 is the ring surrounding the dial 14 and protects thecrystal 26. The bezel 24 rotates relative to the watch dial 14 toprovide other functionality such as for easy time measurement functions.The bezel 24 is considered herein as part of the watch case as it has aprotecting function associated with the watch case. The bezel 24 can beformed of any material, but a metal such as stainless steel allows for adecorative ornamental feature while providing a high degree ofprotection to the watch 10. The coupling between the body 20 and thebezel 24 that allows for rotation is generally known in the watch art.

The crystal 26 of the watch 10 is transparent and is used to protect thewatch dial 14 and hands 16. The crystal 26 can be made of a number oftransparent materials known in the art and provided with coatings toimprove performance and life. The crystal 26 can is, within the meaningof this application, part of the watch case due to the protectivefunctionality.

The frame 30 includes a back frame plate 32 configured to be adjacentthe user, a top frame plate 34 spaced from the back frame plate 32 andincluding a central opening 36 therein for receipt of the main body 20,a pair of lugs 38 on opposed ends of the frame 30, wherein each lug 38extends between the spaced top frame plate 32 and the back frame plate34, and a bar 40 extending between each pair of lugs 38, wherein eachbar 40 is configured to receive a strap (not shown) of a wrist watch.The top frame plate 34 extends to at least partially cover the bezel 24in side view, as best illustrated in FIG. 5.

The back frame plate 32 includes a central opening 42 therein as shown,with a recessed seat 44 which receives the main body 20 therein. Aplurality of spaced threaded fasteners 46 positioned in an annular arrayis used to secure the main body 20 to the frame 30. A portion of thebody 20 is removed from FIG. 1 to illustrate the faster 46 location inthe final assembly.

The back frame plate 32 and the top frame plate 34 have a curvatureextending along each respective plate from end to end as shown. Thewatch 10 includes a stem 50 or crown, coupled to the movement 12 in aconventional fashion. Stem 50 extends through an associated opening inthe cylindrical main body 20 and stem 50 extends from the side into anelongated curved oval shape between the back frame plate 32 and the topframe plate 34.

Additionally, the back frame plate 32 and the bottom plate 22 have acurvature extending along each respective plate from end to end.Additionally the frame 30 completes the open frame design by includingan opening between the top frame plate 34 and the back frame plate 32 onthe ends between each pair of lugs 36. The frame 30 has shown has theback frame plate 32, top frame plate 34 and lugs 38 formed as one piececomponents, and this has certain structural and aesthetic advantages.However these components may be formed as several separable components.For example the top frame plate 34 may be separable from the lugs 38secured thereto with fasteners, or alternatively the lugs may be coupledto the top and back frame plates 34 and 32 through separate elementssuch as a hinged member.

The frame 30 provides an easily replaceable protecting member for themain body 20. Additionally the ornamental aspects of the frame 30provide a particular accent to the watch 10 that can be readily changedwith a change in the frame design 30. The present invention contemplatesswapping distinct frames 30 for use with a single body 12 (and otherassociated watch components). The frame can be formed of numerousmaterials, but metals such as stainless steel allow for aestheticallypleasing appearance and protective functionality. The present designallows the main body 20 to be formed of a metal or other materialdistinct from the metal or other material forming the frame 30 toincrease the complementary design possibilities and to allow each to beselected for its particular functionality. The frame 30 may be formed of17-4 stainless steel that is hardened and exhibits a Rockwell hardnessof about 60.

The bold and innovative design of the watch case of the presentinvention allows the watch 10 to be easily used as a pendent watch orother application. For these alternative uses the frame 30 is replacedwith a chain mounting fob or other base suitable for the desiredapplication, such as a dive control function. The functionality of thewatch case of the present invention is being promoted commercialized asthe CORE AND CAGE™ technology, wherein the CORE™ technology is theseparable body 20 housing the main timekeeping elements and the CAGE™technology is the frame 30 which is designed for protection, wearability and comfort (as well as to aesthetically complement theremaining watch elements).
